摘要：我国现处于一个经济横飞的时代。随着改革开放，经济水平的提高。人们生活水平越来越高，空调等电器也步入百姓家庭，但传统的空调还要人为的去调温度很不方面，已经不能满足现代化的要求;第二传统普通空调使用氟利昂循环制冷，其空气太干燥，使人易患“空调病”；第三传统空调温度控制系统复杂 ， 成本高。本设计采用热敏电阻，滞回比较器等实现恒温控制，电路简单，成本低；避免了手工操作；节能性好。通过热敏电阻测温，测温电桥把测量所得的温度转换成电压信号，经过运算放大器放大后，与设定室温相比较，若低于设定值，吹热风，若高于设定值吹冷风。

ABSTRACT:China is now in an economic flying era. Along with the reform and opening-up, economic level enhancement. People living standard is more and more high, air-conditioning appliances into people, but the traditional family even human to adjustable air temperature is not, cannot have satisfied modern requirements; The second traditional common air conditioning refrigeration, its use of Freon air too dry, make the person are predisposed to "Air conditioning disease"; The third conventional air conditioning temperature control system is complex, high cost. This design USES the thermostats, hysteresis comparator realize temperature control, such as the simple circuit, cost is low; Avoid the manual operation; Energy conservation. Through thermostats temperature measurement, the measurement temperature measurement bridge from the temperature conversion into voltage signal amplifier amplification, through comparing, and setting room temperature, below the set value, blow hot air, if chilling by cold air than setting.
Key words: Controlled air conditioning; circuit design; thermostat; Temperature Bridge; hysteresis voltage comparator
